Episode notes
Sensations Versus Physical Causes
- Sensations like light and color are not physical entities but effects caused by physical waves on our nerves.
- Russell stresses the experienced 'light' is distinct from the wave motion that causes it.
Private Perception Versus Public Space
- The space of perception differs from the physical space used by science and must be distinguished.
- Russell argues physical space is public and distinct from private visual or tactile spaces.
Relative Position Determines Sensation
- For sensations to be caused, sense organs and external objects must occupy positions in one physical space.
- Relative positions in that physical space largely determine the sensations we experience.
